  • Publication number: 20200352868
    Abstract: An object of the present invention is to obtain a capsule for treating ulcerative colitis which, when a capsule containing indigo is orally administered, acts more effectively than conventional ones and has less side effects of hepatotoxicity by not easily disintegrating in the stomach and small intestine but only in the large intestine. The present invention relates to a capsule for treating ulcerative colitis which disintegrates locally in the large intestine, comprising a drug-containing content, a protective layer coating the content and a film formed outside the protective layer, which are arranged concentrically, wherein the content is a content in which indigo, which is a drug for treating ulcerative colitis, is dispersed or dissolved, and the film is locally disintegrated in the large intestine.

  • Publication number: 20200184126
    Abstract: A design support method includes: acquiring reference diagrams which are control logic diagrams created in the past, and an editing object diagram; and applying each of analysis rules to each control logic diagram, and analyzing the control logic part included in each control logic diagram. The analysis rules satisfy a relation in which a control logic part corresponding to an analysis rule at a higher hierarchy level contains a control logic part corresponding to an analysis rule at a lower hierarchy level. The design support method further includes: specifying, as a similar diagram, a reference diagram including a control logic part common with the control logic part included in the editing object diagram, among the reference diagrams, based on an analysis result; and presenting a control logic part having a hierarchical relation with the common control logic part, among control logic parts included in the similar diagram.
